"An ethics lawyer who served in George W. Bush's White House is calling on Congress to investigate President Trump's abrupt dismissal on Tuesday of FBI Director James Comey. Richard Painter tells Rolling Stone the surprise move is a clear-cut abuse of power. "We cannot tolerate this – for the president to be firing people who are investigating him and his campaign and its collusion with the Russians," Painter says. "It's a lot worse than Watergate.
